The present is disintegrating into the troubled past. Time flows, and its flow changes course, but you wouldn't know it from being in it. Shadows cast on a wall.
Final sequence: rapturous and breathtaking -- brings this up from a 3 star film. Beckons you to revisit everything that came before, which I had watched passive and a little impatient from a distance.
Distance partially comes from how little info slips through, and how easily misplaced it is. One-time mentioned figures or memories come up and the film gestures toward the shadow they cast but never directs you to look at it.
